Heating and Thermal Insulation Apparatus

The present disclosure relates to a heating and thermal insulation apparatus.

An existing heating and thermal insulation apparatus is a food ingredient thermal insulation table, a heating plate, or the like. Heating is generally implemented by using a heating wire embedded in a housing, but an existing heating wire is generally located in a preset embedded slot. A shape of a slot body is adapted by glue injection or buckling to implement heating wire fastening.

However, there is still a lack of structural stability by setting the embedded slot in the housing. In a case that injected glue falls off or assembly is not in place, the heating wire is prone to fall off due to movement of the food ingredient thermal insulation table or the heating plate. Especially, when the foregoing structure is applied to a flexible thermal insulation apparatus, in a process that the flexible thermal insulation apparatus is repeatedly folded or rolled up, the heating wire is prone to be offset in position, so that a subsequent heating effect is affected, and a service life of the heating and thermal insulation apparatus is affected.

To overcome the disadvantages in the prior art, the present disclosure provides a heating and thermal insulation apparatus.

By pouring silicone rubber in the heating wire, the heating wirein the elastic pouring layer is in close contact with the silicone rubber part, so that a situation of position offset is not prone to occur.

The heating contact surface, the placement surfaceand the heat source layer are at least made of a flexible material. As a preferred solution rather than a limitation, all materials of the heating bodyin the embodiment are flexible materials, where the heating wireincludes an electric wire and an insulation material that wraps the electric wire.

In addition, when the heating and thermal insulation apparatus in the embodiment is placed on a table in a forward direction, from a perspective of a user, only the flexible top plateis exposed out of the heating bodyas a whole, thereby improving an integrated effect of the heating and thermal insulation apparatus in the embodiment of the present disclosure, and improving using experience of the user. The flexible top plateis made of silica gel, PE, TPE or PLA.

As a specific solution rather than a limitation, the placement surfaceincludes a placement surface bodylocated at the bottom of the heating body, and a plurality of support bulgesprotruding downward from the placement surface body. A heat dissipation channel is formed between the support bulges. In the embodiment, the heating bodyis raised by the support bulge, so that a heat dissipation channel is formed between the support bulgebelow the heating body, thereby facilitating heat dissipation at the bottom of the heating and thermal insulation apparatus and improving product stability.

In some embodiments, the support bulgeand the bulge bodymay be integrally formed and made of a same material. For example, the support bulgemay be a U-shaped stand column.

As a specific solution rather than a limitation, the heating bodyhas a thickness of smaller than 5 cm, and a laying area of the working partof the heating wireis greater than 60% of a surface area of the heating body. Preferably, the thickness of the heating bodyin the embodiment is a sum of a thickness of the flexible top plateand a thickness of the placement surface. The heating bodyhas a thickness of about 2-3 cm. The paving area of the working partof the heating wireis greater than 80% of the surface area of the heating body.

As a specific solution rather than a limitation, the insulation housingincludes an upper housingand a lower housing, and an openinginto that a side edge of the heating bodystretches is formed between the upper housingand the lower housing. The insulation housingis disposed at a short side of the heating body, and the short side of the heating bodystretches into the opening. By providing the short side of the openingto stretch into the heating body, a combination of the heating bodyand the insulation housingis closer while a good integrated effect is ensured.

In the embodiment, a notchis formed at the short side, and the first endand the second endof the connecting partstretch out of the notchand enter into the insulation housingto be electrically connected to the power supply component.

A working part of the heating wire is located on the heat source layer and is tightly wrapped by the heat source layer. For example, the heat source layer may be an elastic pouring layer or an implant layer. The heating wire may be poured simultaneously with the heat source layer or buried in the heat source layer in an implanted manner, so as to implement close contact between the heating wire and the heat source layer. The heating wire is not prone to fall off due to movement of the heating and thermal insulation apparatus.
